Vulnerability from csaf_redhat - Published: 2026-06-16 09:06 - Updated: 2026-06-16 09:37Summary
Red Hat Security Advisory: Technical preview of the satellite/iop-vulnerability-frontend-rhel9 container image
Severity
Important
Notes
Topic: A new satellite/iop-vulnerability-frontend-rhel9 container image is now available as a technical preview in the Red Hat container registry.
Details: Red Hat Lightspeed in Satellite analyzes system health and configuration by applying predefined rules to a small set of local data, such as installed packages, running services, and configuration settings.

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by crafting a malicious Uniform Resource Identifier (URI) that contains percent-encoded authority delimiters. The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw separators, which can change the URI's intended authority. This issue allows applications that perform host allowlist checks, redirect validation, or outbound request routing to be steered to a different authority than specified, potentially bypassing security controls.

Threats
Impact
Important
A flaw was found in the shell-quote component. The quote() function did not properly validate object-token inputs, allowing line terminators to pass unescaped into the output. A remote attacker could exploit this vulnerability by providing specially crafted input, which a POSIX shell would interpret as a command separator. This could lead to command injection, enabling the attacker to execute arbitrary code on the system.

Impact
Important
A flaw was found in minimatch. A remote attacker could exploit this Regular Expression Denial of Service (ReDoS) vulnerability by providing a specially crafted glob pattern. This pattern, containing numerous consecutive wildcard characters, causes excessive processing and exponential backtracking in the regular expression engine. Successful exploitation leads to a Denial of Service (DoS), making the application unresponsive.

Impact
Moderate
A flaw was found in minimatch. A remote attacker could exploit this vulnerability by providing a specially crafted glob expression with nested unbounded quantifiers. This could lead to catastrophic backtracking in the V8 JavaScript engine, causing the application to become unresponsive and resulting in a Denial of Service (DoS).

Impact
Moderate
A flaw was found in Immutable.js, a library for persistent immutable data structures. This vulnerability, known as Prototype Pollution, allows an attacker with low privileges to inject unwanted properties into core JavaScript object prototypes without user interaction. By manipulating specific APIs such as mergeDeep(), mergeDeepWith(), merge(), Map.toJS(), and Map.toObject(), a remote attacker could potentially execute arbitrary code or cause a denial of service (DoS).

Threats
Impact
Important
A flaw was found in marked, a markdown parser and compiler. An unauthenticated attacker can exploit this Denial of Service (DoS) vulnerability by providing a specific 3-byte input sequence (a tab, a vertical tab, and a newline). This input triggers an infinite recursion loop during parsing, leading to unbounded memory allocation and causing the host Node.js application to crash due to Memory Exhaustion (OOM).

Threats
Impact
Moderate
A flaw was found in Axios, an HTTP client library. This vulnerability allows an attacker to exploit a prototype pollution issue if another part of the application has already polluted the Object.prototype. By doing so, the attacker can intercept and modify JSON responses or take control of the HTTP communication. This could lead to unauthorized access to sensitive information like user credentials and request details.

Impact
Important
A flaw was found in Axios, a software library for making network requests. A remote attacker can exploit a prototype pollution vulnerability to inject arbitrary HTTP headers into outgoing requests. This occurs when the application's core object definitions are manipulated, causing Axios to misinterpret data and include attacker-controlled headers in network communications. This could lead to unauthorized actions or data manipulation.

Threats
Impact
Moderate
A flaw was found in Axios, a promise-based HTTP client for browsers and Node.js. This vulnerability occurs because the `toFormData` function recursively processes nested objects without a depth limit. A remote attacker can exploit this by sending deeply nested request data, which causes the Node.js process to crash due to a RangeError, leading to a potential Denial of Service (DoS) if the process crashes.

Threats
Impact
Important
A flaw was found in Axios, a promise-based HTTP client. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to manipulate the `Object.prototype.validateStatus` property. By polluting this property, all HTTP error responses (such as 401, 403, or 500) are silently treated as successful responses. This can lead to a complete bypass of application-level authentication and error handling, potentially granting unauthorized access.

Threats
Impact
Important
A flaw was found in Axios, a promise-based HTTP client. An attacker who can control the destination address of an Axios request can exploit this vulnerability. By using specific internal network addresses (within the 127.0.0.0/8 range, excluding 127.0.0.1), the attacker can completely bypass the NO_PROXY protection, potentially leading to unauthorized access or information disclosure within the network. This issue is an incomplete fix for a previous vulnerability.

Impact
Important
A flaw was found in Axios, a widely used HTTP client. This vulnerability, known as a Prototype Pollution "Gadget" attack, allows a remote attacker to subtly alter JSON API responses. By manipulating a specific function, an attacker can selectively modify data within these responses. This could lead to significant security breaches, including unauthorized privilege escalation, fraudulent balance manipulation, or bypassing critical authorization checks.
